Andrew Jackson had personal advisers that could not be approved as member of his Cabinet by the Senate. So he chose personal advisers that met in the Kitchen. They became known as the Kitchen Cabinet. You must know that Andrew Jackson was a very rough frontier man and his friends were also. So when he brought his friends to Washington D. C. the established society was distressed to say the least. At his inauguration the people climbed on the furniture with their muddy boots. They left the White House in a mess. There was no way the Senate would approve "that kind of a man" as a member of the official Presidential Cabinet. He rarely met with the paid official Presidential Cabinet. .

The term "Kitchen Cabinet" refers to the name give to President Andrew Jackson's informal advisers. His critics felt he relied on these advisers more than he did his official cabinet.
No. Article I deals with Congress, so I assume you are referring to Article II, which is still "No." The Presidential Cabinet is completely outside the descriptions of the Executive as provided by the Constitution. President Washington wanted to bring advisers into the Presidency with him to oversee certain matters and they would discuss policy decisions in the Kitchen (whence the term "Cabinet" comes). The decision to have such advisers was lauded by other politicians and the practice has become a cemented part of the system even if it is not explicitly provided for by the letter of the Constitution.
